The thing that ___ for the signal is pretty simple. Special kind of transistor is called field effect transistors are ___ to their environment making some changes in their environment when something in their environment changes like a new molecule is introduce then their ability to conduct the electricity changes. If you can measure how much electricity is going through one part of this transistors then you measure what the transistor is sensing. That is, that is the easy part. The harder part is making a transistor specific for an order molecule in your case knows(?). The molecule mucus(?) layer helps catch up reproductive.
